QED yet again continue to bring their excellent research results into the development of a new cable. The QED Reference Quartz Optical boasts a first of its kind Glasscore™ technology - a conductor packed with 210 boro-silicate glass fibres. This cable massively exceeds the bandwidth required for high definition surround sound broadcasts meaning stunning sound if you're using it to connect sources to AV amplifiers.

Glasscore™ Technology - Straighter Paths, Less Jitter

Conventional optical fibres are usually made from an acrylic glass material known as PMMA. The acrylic core allows the light to take many different length paths through the cable which is fine for most regular digital audio signals but does increase timing differences and jitter which high quality equipment will pick up on. Glasscore™ uses 210 tiny fibres smaller than a human hair which direct the signal down a straighter path through the cable keeping jitter to a minimum and delivering perfectly timed audio.

QED have proven with undoubted success their ability to nurture and develop award-winning technologies. This time, Glasscore™ technology employs multiple bundles of ultra-fine boro-silicate glass optical fibres to send the differing light rays on a similar path which virtually eliminates timing error and results in less distortion and jitter.

The QED Reference Quartz Optical also supports 12MHz bandwidth, over double the capacity of conventional digital optical cables using single acrylic glass fibres. Multi-channel HD audio will sound as good as it possibly can do.
